Topographic stress
WebFigure 9. Maps of the Calhoun site showing (a) elevation, (b) mean negative curvature calculated from a smoothed topographic surface, and (c) the depth to a least compressive stress of 0.5 MPa (DLCS) calculated with tectonic stress conditions of math formula = 6.25 MPa, math formula = 4 MPa with H oriented N65°E. WebMar 9, 2015 · If topographic stresses are significant and produce shear in the direction of fault slip, then for given values of static friction and pore fluid pressure, we can calculate the amount of tectonic stress that can be added to the ambient stress field before the faults should rupture; given limited acceptable ranges for friction and fluid pressure ...

Secondly, only a few studies have included topographic stress perturbations due to the complicated geometry, either analytically [19,45], or numerically [8,17,18], and they are mostly in 2D.
WebDec 10, 2002 · Theoretical calculations have shown that the presence of topographic features such as ridges and valleys can cause vertical and lateral variations in the shallow subsurface stress field (15) and ...
